Description

TECHNICAL FIELD

The present disclosure relates to a field of mousetrap technology, and in particular to a bidirectional linkage type mousetrap.

BACKGROUND

A conventional mousetrap generally includes a bottom plate, a clip arranged on the bottom plate, and a trigger plate. When a mouse steps on the trigger plate, the clip closes immediately to capture the mouse. However, such a mousetrap is easy to clip to pets and children because it has no protective cover.
For this reason, there are also some mousetraps with protective shells on the market. Mouse clips are installed inside the protective shell. When the mouse enters into the protective shell and touches the mousetrap, it is captured by the mousetrap. However, existing mousetraps have the following disadvantages: 1. The mousetrap generally only includes one inlet, which reduces probability of catching mice, and efficiency of catching mice is not high. 2. When the mouse enters the mouse clap, it can only trap the mouse, but not kill the mouse by trapping. 3.

This structure better forces the mouse to press one pedal 3, which is advantageous for trapping the mouse, and also enables the discharge opening 22 of the upper shell 2 to be positioned closer to the bait placing cup 6, which facilitates a placement of the baits.
A working principle of the present disclosure is as follows:
In use, the user can press the upper shell 2, so that the upper shell 2 is closed with the base 1, and the two clamping shafts 4 are respectively engaged in the clamping shaft accommodating grooves 31 of the first pedal 3 a and the second pedal 3 b, and the clamping shaft buckles 32 clamps the clamping shafts 4, which restrict the clamping shafts 4 and the upper shell 2 from bouncing upward. At this time, the torsion springs 5 are compressed, the inward ends of the first pedal 3 a and the second pedal 3 b are tilted upward, the first pedal 3 a and the second pedal 3 b are tilted, and the mousetrap is in a configuration of use, as shown in FIG. 1.
When the mouse enters from any of the two mousetrap inlets 21, the mouse presses one of the first pedal 3 a or the second pedal 3 b that is corresponding to the mousetrap inlet, e. g., the mouse enters from one inlet corresponding to the first pedal 3 a, and steps on the first pedal 3 a. At this time, the first pedal 3 a simultaneously presses down the second pedal 3 b on the other side to achieve linkage. When the first pedal 3 a and the second pedal 3 b are depressed and flipped, the clamping shaft buckles 32 of the first pedal 3 a and the second pedal 3 b unwind the restriction on the clamping shafts 4, and under elastic reset of the torsion springs 5, the clamping shafts 4 and the upper shell 2 are bounced upward. the clamping shafts 4 are engaged with the corresponding clamping racks 72 to clip the mouse until the mouse is killed, as shown in FIGS. 11 and 12.
When the mouse is killed, as long as the upper shell 2 is pressed, the clamping shafts 4 are moved downward to facilitate pulling out the mouse.
In summary, the present disclosure is with novel structure and is convenient to use. The present disclosure is a clamping mechanism having two inlets and two-way linkage, which increase the probability of catching the mouse and is able to kill the mouse, and has high efficiency. The user is able to judge whether the mouse is captured according to the position of the upper shell, that is, the present disclosure has a reminder function.
